During long, slow distance training, you should think of yourself as a thoroughbred disguised as a plow horse. No need to give yourself away by running fast.
There are no secrets to running success,anyone who says there are is probably trying to sell you something.
The endurance athlete is the ultimate realist.
Road racing is rock 'n roll; track is Carnegie Hall.
You've got to be a little bored to be doing really good training.
There's no satisfaction without a struggle first.
